only the absolute broadband-elite can afford a daily download of 700MB. the regular BT user may download a movie of that size every now and then...the typical size for a show of that length that you download on a daily basis, is about half of that. consider the releases of jon stewart's daily show - the torrents come at 170MB for a 25min show. peak at 1000+ peers.

you could even consider posting a 700MB and an 200-300MB torrent - the traffic you've got now wouldn't devide up between the two, you would gain a lot of peers that can't afford the 700MB download but still prefer to the webstream a file they can store and share ...
